Below, will describe by together as the control algorithm of the performed program of the SBW-ECU 1000 of the controller of vehicle of first example embodiment and ECB-ECU 1300 in conjunction with Fig. 4.
At first, in step 100 (" step " below will abbreviate " S " as), ECB-ECU1300 judges whether main power source 200 is in the power supply trouble state.If main power source 200 is in power supply trouble state (S100: be), then control program proceeds to S102.Otherwise (S100: not), the current loop ends of control program.
In S102, ECB-ECU 1300 judges whether the speed of a motor vehicle is lower than preset vehicle speed V (0).If the speed of a motor vehicle is lower than preset vehicle speed V (0) (S102: be), then control program proceeds to S106.Otherwise (S102: not), program proceeds to step S104.
In S104, whether ECB-ECU 1300 judgements are lower than predetermined voltage Vecb (0) from the voltage Vecb that ECB cond 204 supplies to the electric power of ECB-ECU 1300.Be lower than predetermined voltage Vecb (0) (S104: be) if supply to the voltage Vecb of ECB-ECU 1300, then control program proceeds to S106.Otherwise (S104: not), control program proceeds to S102.
In S106, ECB-ECU 1300 starts (power supply is given) relay circuit 206.Then, in S108, SBW-ECU 1000 judges whether P-switch 1100 is operated.If P-switch 1100 has been operated (S108: be), then control program proceeds to S116.Otherwise (S108: not), control program proceeds to S110.
In S110, SBW-ECU 1000 judges whether chaufeur or other passengers are intended to get off.More specifically, seat detection signal or car door on/off signal indicates chaufeur or other passengers have left his or her seat, SBW-ECU 1000 determine his or she intention and get off.Get off (S110: be) if determine chaufeur or other passengers intention, then control program proceeds to step S116.Otherwise (S110: not), program proceeds to step S112.
In S112, SBW-ECU 1000 judges whether the speed of a motor vehicle is lower than preset vehicle speed V (1).If the speed of a motor vehicle is lower than preset vehicle speed V (1) (S112: be), then control program proceeds to S116.Otherwise (S112: not), program proceeds to S114.
In S114, SBW-ECU 1000 judges whether the voltage Vsbw of SBW accessory feed 202 is lower than predetermined voltage Vsbw (0).If the voltage Vsbw of SBW accessory feed 202 is lower than predetermined voltage Vsbw (0) (S114: be), then control program proceeds to S116.Otherwise (S114: not), control program turns back to S108.
In S116, SBW-ECU 1000 carries out the control of P-gear, and actr 42 is activated with pivot detent plate 100 in described P-gear control, thereby makes roller 112 move to P-position otch 124.
Below the operation of the controller of vehicle of first example embodiment will be described based on above-mentioned structure and control algorithm.
(S100: not), then SBW-ECU1000 and ECB-ECU 1300 just can utilize the operation power of supplying with from main power source 200 as long as main power source 200 is in normal condition.When by main power source 200 power supplies, described SBW-ECU 1000 utilizes the power start SBW actr of supplying with from main power source 200 during by driver's operation when P-switch 1,100 1200, and ECB-ECU 1300 utilizes as brake pedal power start ECB 1400 from main power source 200 supplies during by driver's operation.
When the power supply trouble of main power source 200 occurring (S100: be), the speed of a motor vehicle is detected.At this moment, ECB cond 204 begins to feed electrical power to ECB-ECU 1300.If the detected speed of a motor vehicle is equal to or higher than preset vehicle speed V (0) (S102: not), then detect the voltage Vecb that supplies to ECB-ECU 1300 subsequently.That is, because main power source 200 is in the power supply trouble state at present, so detected from the voltage Vecb of ECB cond 204 supplies.(S102: not), the voltage Vecb that then supplies to ECB-ECU 1300 is detected if detected voltage Vecb is equal to or higher than predetermined voltage Vecb (0).That is, detected from the voltage Vecb of ECB cond 204 supplies.(S104: not), control program just proceeds to S106 in the time of then under the speed of a motor vehicle drops to preset vehicle speed V (0) if detected voltage Vecb is equal to or higher than predetermined voltage Vecb (0).
On the other hand, if the speed of a motor vehicle is lower than preset vehicle speed V (0) (S102: be) or detected voltage Vecb be lower than predetermined voltage Vecb (0) (S104: be), 202 beginnings of then starting relay circuit 206 (S 106) subsequently, so SBW accessory feed are to the SBW-ECU1000 supply capability.
Then, as long as P-switch 1100 be not operated (S108: not), chaufeur or other passengers' the intention of getting off be not detected (S110: not), the speed of a motor vehicle keep being equal to or higher than preset vehicle speed V (1) (S 112: not) and the voltage Vsbw of SBW accessory feed 202 keep being equal to or higher than predetermined voltage Vsbw (0) (S114: not), then control program just do not proceed to S116.
The intention of getting off that just is being operated (S108: be), chaufeur or other passengers when P-switch 1100 is detected voltage Vsbw that (S110: be), the speed of a motor vehicle drop to (S112: be) under the preset vehicle speed V (1) or SBW accessory feed 202 when dropping under the predetermined voltage Vsbw (0) (S114: be), and P-ON gear control (control of parking-ON gear) is performed.P-ON gear control start SBW actr 1200 so that gear from non-P position change to the P position.More specifically, at this moment, the protrusion of parking locking rod 106 is fixed between the tooth of parking spreadet spreadet wheel 108, so drive wheel is locked and can not rotate.Thereby the stabilized conditions that keeps vehicle.
Controller of vehicle according to above-mentioned first example embodiment, even when the power supply trouble that main power source occurs and therefore the SBW actr become when not moving, also can switching relay, so that the SBW actr utilizes the operation power of supplying with from the SBW accessory feed, therefore gearshift keeps and can move at least.Therefore, the situation that can avoid the power supply trouble owing to main power source to make stop mechanism and gearshift all become and not move.Therefore, even the power supply trouble of main power source occurs, still can keep the stabilized conditions of vehicle according to the intention of chaufeur.In this case, according to the controller of vehicle of first example embodiment, during the power supply trouble of main power source, at least one maintenance in stop mechanism and the gearshift can move.
Further, when main power source is in normal condition, perhaps when the electric power of ECB cond does not also exhaust, keep the stabilized conditions of vehicle by stop mechanism.Therefore, in this case, be interrupted, still can keep the stabilized conditions of vehicle even the electric power between SBW accessory feed and the SBW-ECU is supplied with to connect.By doing like this, make must the using of electric power of SBW accessory feed minimize.
Simultaneously, when vehicle laterally or the amount of exercise on steering direction when exceeding predetermined amount of exercise (for example, yaw amount (yaw amount)), SBW-ECU is applicable to the use of forbidding the SBW actr.For example, (for example have when vehicle on the road surface of friction coefficient, when the road surface that ice is arranged) moving on horizontal or steering direction, start parking lock from non-P position change to the P position and therefore if the SBW actr is activated with the gear with change-speed box, then vehicle may slide.Yet, if being applicable under the condition that vehicle is not having on horizontal or the steering direction to move, the SBW actr moves, can prevent this slip of vehicle.Can utilize G-sensor and yaw rate sensor to detect the cross motion amount of vehicle and the amount of exercise of steering direction.
Further, when detecting chaufeur or other passengers intention when getting off when (for example, chaufeur has left his or her seat, car door just is opened), SBW-ECU goes for starting the SBW actr.In this case, prevent gear when vehicle moves from non-P position change to the P position.That is, prevent that parking lock is activated when vehicle moves.
Further, driver intention stops vehicle (for example, using braking in the P position) and when detecting chaufeur or other passengers when being intended to get off, SBW-ECU goes for starting the SBW actr when detecting.In this case, also prevented to stop to be locked at when vehicle is moving to be activated; On the other hand, the stabilized conditions that when vehicle is in stabilized conditions, keeps vehicle.
When the voltage of supplying with from the SBW accessory feed dropped under the predetermined voltage Vsbw (0), it is depleted that the controller of vehicle of first example embodiment determines the electric power of SBW accessory feed.Therefore, by utilizing the SBW actr to make the parking locking rod move locking parking spreadet spreadet wheel in advance to keep the stabilized conditions of vehicle.
Below, with the controller of vehicle of describing according to second example embodiment of the present invention.The vehicle of controller of vehicle that combines second example embodiment is different with the vehicle of the controller of vehicle that combines first example embodiment, reason is not to be provided with the SBW accessory feed and detects given enabled condition when being satisfied as ECB-ECU in the vehicle of the controller of vehicle that combines second example embodiment, electric power is supplied to SBW-ECU from the ECB cond.Other assemblies of vehicle of controller of vehicle that combine second example embodiment are identical with the assembly and the part of the vehicle of the controller of vehicle that combines first example embodiment with part.Public assembly with identical function is represented with identical Reference numeral with part, and is not described in detail.
Especially, the controller of vehicle of second example embodiment is characterised in that: when given enabled condition was satisfied, ECB-ECU 1300 supplied to SBW-ECU 1000 with electric power from ECB cond 204.When in the vehicle of second example embodiment, SBW accessory feed 202 not being set, on the contrary SBW accessory feed 202 can be set.In this case, the controller of vehicle of second example embodiment can move in the following cases effectively: the situation that has descended and therefore made SBW-ECU 1000 and SBW actr 1200 utilize the electric power of SBW accessory feed not move owing to the reason of the shortage of the electric power of SBW accessory feed or other power failures at the voltage of SBW accessory feed for example.
When the voltage Vecb of ECB cond 204 was lower than predetermined upper voltage limit Vecb (2) but is equal to or higher than with predetermined lower bound voltage Vecb (3), the enabled condition of second example embodiment was satisfied.Predetermined upper voltage limit Vecb (2) is corresponding to the lower limit of the operating voltage of ECB 1400, and predetermined lower bound voltage Vecb (3) is equal to or higher than the lower limit of the operating voltage of ECB-ECU 1300.
Below, the control algorithm of the program of being carried out by the ECB-ECU 1300 as the controller of vehicle of second example embodiment will be described in conjunction with Fig. 5.
At first, in S200, ECB-ECU 1300 judges whether main power source 200 is in the power supply trouble state.If main power source 200 is in power supply trouble state (S200: be), then control program proceeds to S202.Otherwise (S200: not), the current loop ends of control program.
In S202, ECB-ECU 1300 judges whether the voltage Vecb of ECB cond 204 is lower than predetermined upper voltage limit Vecb (2).If the voltage of ECB cond 204 is lower than predetermined upper voltage limit Vecb (2) (S204: be), then control program proceeds to S206.Otherwise (S202: not), control program proceeds to S204.
In S204, ECB-ECU 1300 forbids from ECB cond 204 to SBW-ECU 1000 supply capabilities, makes SBW-ECU 1000 utilize the electric power of supplying with from ECB cond 204 not move.At this moment, the electric power of ECB cond 204 is used for 1400 power supplies to ECB.
On the other hand, in S206, ECB-ECU 1300 judges whether the voltage Vecb of ECB cond 204 is lower than predetermined lower bound voltage Vecb (3).If the voltage Vecb that supplies with from ECB cond 204 is lower than predetermined lower bound voltage Vecb (3) (S206: be), then control program proceeds to S210.Otherwise (S206: not), control program proceeds to S208.
In S208, ECB-ECU 1300 permissions to SBW-ECU 1000 supply capabilities, make 204 beginnings of ECB cond to SBW-ECU 1000 supply capabilities from ECB cond 204.Therefore, if chaufeur is operated P-switch 1100 under described state, then SBW-ECU 1000 carries out following P-ON gear control: utilize the power start SBW actr 1200 that comes from the ECB cond with gear from non--P position change to the P position.It should be noted, be lower than in the speed of a motor vehicle under the situation of preset vehicle speed (that is, being ON) that when detecting vehicle when stablizing in fact, SBW-ECU 1000 selectively is applicable to and carries out described P-ON gear control if vehicle stops determination flag.
On the other hand, in S210, ECB-ECU 1300 determines SBW-ECU1000 and can not utilize the electric power that comes from ECB cond 204 to carry out the control of P-ON gear.Therefore, in this case, SBW-ECU 1000 can not be by 204 power supplies of ECB cond.
Below, will operation based on the controller of vehicle of second example embodiment of said structure and control algorithm be described in conjunction with Fig. 6.
In Fig. 6, main power source 200 normal operations are up to moment T (0) (S200: not).Therefore, up to moment T (0), SBW-ECU 1000 and ECB-ECU 1300 utilize the operation power of supplying with from main power source 200.That is, SBW-ECU 1000 utilizes the power start SBW actr of supplying with from main power source 200 1200 in response to P-switch 1100 is operated, and ECB-ECU 1300 utilizes the power start ECB 1400 that supplies with from main power source 200 in response to brake pedal is operated.
Then, when locating to occur the power supply trouble of main power source 200 at moment T (0) (S200: be), 204 beginnings of ECB cond are to ECB-ECU 1300 supply capabilities.Thereafter, the voltage Vecb of ECB cond 204 is along with ECB cond 204 continues to descend to the ECB-ECU1300 supply capability.
To moment T (1), the voltage Vecb of ECB cond 204 is equal to or higher than predetermined upper voltage limit Vecb (2) (S202: not) from moment T (0).Therefore, during this section, ECB cond 204 is forbidden to SBW-ECU 1000 supply capabilities (S204).
To moment T (3), the voltage Vecb of ECB cond 204 is lower than predetermined upper voltage limit Vecb (2) (S202: be) but is equal to or higher than (the S206: not) with predetermined lower bound voltage Vecb (3) from moment T (1).Therefore, during this section, ECB cond 204 allows to SBW-ECU 1000 supply capabilities (S208).
Therefore, if chaufeur is operated P-switch 1100 in this state, then utilize the power start SBW actr 1200 that comes from ECB cond 204.Because SBW actr 1200 utilizes the electric power of ECB cond 204, so hypothesis SBW actr 1200 is being located to be activated such as moment T (2), then the decreasing ratio of voltage Vecb increases shown in the dotted line of Fig. 6.
At moment T (2) afterwards, the voltage Vecb of ECB cond 204 drops under the lower limit of operating voltage of ECB-ECU 1300, and therefore no longer detects the speed of a motor vehicle.Therefore, be stopped (S210) to the electric power supply of SBW-ECU 2000 from ECB cond 204.
According to the controller of vehicle of aforesaid second example embodiment, during the power supply trouble of main power source, the level of power that needs only the ECB cond is in the scope to the ECB power supply, and the ECB cond just is under an embargo to the SBW-ECU supply capability.Therefore, in the meantime, there is not the interference of ECB operation, and therefore keeps the stabilized conditions of vehicle by ECB.Subsequently, if the level of power of ECB cond drops under the lower limit of powering to ECB, then the electric power of ECB cond just is fed into SBW-ECU, and SBW-ECU starts gearshift.That is, at this moment, SBW-ECU utilizes the power start parking lock of ECB cond, thereby keeps the stabilized conditions of vehicle.
Simultaneously, when the amount of exercise of vehicle on horizontal or steering direction exceeded predetermined amount of exercise (for example, the yaw amount), SBW-ECU went for forbidding the use of SBW actr.For example, (for example have when vehicle on the road surface of friction coefficient, when the road surface that ice is arranged) moving on horizontal or steering direction, start parking lock from non-P position change to the P position and therefore if the SBW actr is activated with the gear with change-speed box, then vehicle may slide.Yet,, can prevent this slip of vehicle if move under the condition that the SBW actr is not having on horizontal or the steering direction to move at vehicle.Can utilize G sensor and yaw rate sensor to detect the cross motion amount of vehicle and the amount of exercise of steering direction.
Controller of vehicle according to the 3rd example embodiment of the present invention will be described below.The vehicle of controller of vehicle that combines the 3rd example embodiment is different on the content of enabled condition with the vehicle of the controller of vehicle that combines second example embodiment.Other assemblies of vehicle of controller of vehicle that combine the 3rd example embodiment are identical with the assembly and the part of the vehicle of the controller of vehicle that combines second example embodiment with part.Public assembly with said function is represented with identical Reference numeral with part, and is not described in detail.
The enabled condition of the 3rd example embodiment is that the voltage Vecb of ECB cond 204 is equal to or higher than predetermined lower bound voltage Vecb (3) and estimates not need to move afterwards ECB1400.That is, the 3rd example embodiment is characterised in that, even when the electric power of ECB cond 204 is enough to actr power supply to ECB 1400, if predetermined enabled condition is satisfied, then the electric power of ECB cond 204 also has been used to move the SBW actr.
When existing indication to stop by ECB 1400 that the record of vehicle and vehicle are current to be in stabilized conditions, chaufeur and to have depressed brake pedal and reach preset time or longer and chaufeur and represent that he or she is intended to keep the stabilized conditions of vehicle the power supply trouble of main power source 200 after, the condition of " estimating not need to move afterwards ECB1400 " is considered to satisfied.
If it is ON that vehicle stops determination flag, then ECB-ECU 1300 determines vehicle and once was stopped.ECB-ECU 1300 judges based on the vehicle speed signal that comes from vehicle-wheel speed sensor whether vehicle is stable at present.
Further, whether ECB-ECU 1300 continues brake pedal to depress equaling greater than the scheduled operation amount and to be longer than the amount of the schedule time based on the pedal stroke signal determining that comes from brake-pedal-travel sensor 214.
If any condition in the following condition is effective, then the condition of " chaufeur represents that he or she is intended to make vehicle remain on stabilized conditions " is considered to effective: the P position is selected, EPB is in operation, chaufeur has left his or her seat and brake pedal is effectively depressed.Judge that based on the operational ton of brake pedal whether brake pedal is by strong depressing.Further, when the car door of vehicle be open the time, the condition of " chaufeur represents that he or she is intended to make vehicle remain on stabilized conditions " also is considered to effective.
Below, the control algorithm of the program of being carried out by the ECB-ECU 1300 as the controller of vehicle of the 3rd example embodiment will be described in conjunction with Fig. 7.
In the diagram of circuit of Fig. 7, the process identical with process in the diagram of circuit of Fig. 5 represented by identical number of steps, and is not described in detail.
In S300, ECB-ECU judges whether the voltage Vecb of ECB cond 204 is lower than and predetermined lower bound voltage Vecb (3).If the voltage Vecb of ECB cond 204 is lower than with predetermined lower bound voltage Vecb (3) (S300: be), then control program proceeds to S210.Otherwise (S300: not), control program proceeds to S302.
In S302, ECB-ECU 1300 judges whether enabled condition is satisfied.The details of described condition is described in the above, therefore is not repeated herein.
In S304, ECB-ECU 1300 allows from ECB cond 204 to SBW-ECU 1000 supply capabilities, so that ECB cond 204 begins to SBW-ECU 1000 supply capabilities via ECB-ECU 1300.Therefore, if operate P-switch 1100 in this state, then SBW-ECU 1000 carries out following P-ON gear control: utilize the power start SBW actr 1200 that comes from the ECB cond so that the gear of change-speed box from non--P position change to the P position.It should be noted that when detecting vehicle essence under the situation that is lower than preset vehicle speed in the speed of a motor vehicle when stablizing, SBW-ECU 1000 selectively is applicable to and carries out described P-ON gear control.After step S304, control program proceeds to S300.
Below, will operation based on the ECB-ECU 1300 of the controller of vehicle of the 3rd example embodiment of said structure and control algorithm be described in conjunction with Fig. 8.
With reference to Fig. 7, main power source 200 normal operations are up to moment T (3) (S200: not).Therefore, up to moment T (3), SBW-ECU 1000 and ECB-ECU 1300 utilize the operation power of supplying with from main power source 200.Promptly, SBW-ECU 1000 utilizes the power start SBW actr of supplying with from main power source 200 1200 in response to P-switch 1100 is operated, and ECB-ECU 1300 utilizes the power start ECB 1400 that supplies with from main power source 200 in response to brake pedal is operated.
Then, when locating to occur the power supply trouble of main power source 200 at moment T (3) (S200: be), 204 beginnings of ECB cond are to ECB-ECU 1300 supply capabilities.Afterwards, the voltage Vecb of ECB cond 204 is along with ECB cond 204 continues to descend to the ECB-ECU1300 supply capability.
During from moment T (3) to moment T (5), the voltage Vecb of ECB cond 204 is equal to or higher than predetermined lower limit voltage Vecb (3) (S300: not), and therefore judge whether enabled condition is satisfied (S302).
Depressed when existing indication after the power supply trouble state appears in main power source 200, to stop current stabilized conditions, the chaufeur of being in of record, the vehicle of vehicle that brake pedal reaches preset time or longer and chaufeur represents that he or she (for example is intended to get off by ECB, chaufeur has left his seat) time, enabled condition is satisfied (S302: be).In this case, therefore, allow from ECB cond 204 to SBW-ECU 1000 supply capabilities, so that 204 beginnings of ECB cond are to SBW-ECU 1000 supply capabilities.Therefore, at moment T (4) afterwards, the decreasing ratio of voltage Vecb increases shown in the dotted line of Fig. 8.If chaufeur is operated P-switch 1100 in this state, then SBW actr 1200 utilizes the electric power of supplying with from ECB cond 204 to be activated.
In moment T (5), the voltage Vecb of ECB cond 204 drops under the lower limit of operating voltage of ECB-ECU, and therefore no longer detects the speed of a motor vehicle.Therefore, 100 electric power is supplied with and is stopped (S210) from ECB cond 204 to detent plate.
According to the controller of vehicle of the 3rd example embodiment, as mentioned above, even when the voltage of ECB cond is enough to power to ECB, continue to be satisfied if estimate the condition that does not need to move ECB afterwards, then electric power still is fed into SBW-ECU from the ECB cond.Therefore, the control of P-ON gear is performed immediately after the power supply trouble state appears in main power source, and therefore can keep the stabilized conditions of vehicle.
In the 3rd example embodiment, when allowing in response to predetermined condition is satisfied from the ECB cond during to the SBW-ECU supply capability, described configuration is not limited to the ECB cond.For example, because vehicle not only comprises ECB but also comprise various systems and the assembly with accessory feed, the accessory feed of described system and assembly can be used to replace the ECB cond.These other system and assembly is such as steer-by-wire type steering hardware, air bag system and siren horn.
Simultaneously, when the amount of exercise of vehicle on horizontal or steering direction exceeded predetermined amount of exercise (for example, the yaw amount), SBW-ECU went for forbidding the use of SBW actr.For example, (for example have when vehicle on the road surface of friction coefficient, when the road surface that ice is arranged) moving on horizontal or steering direction, start parking lock from non-P position change to the P position and therefore if the SBW actr is activated with the gear with change-speed box, then vehicle may slide.Yet, if the SBW actr only be applicable to when vehicle in operation during not in motion on horizontal or the steering direction, can prevent this slip of vehicle.Can utilize G sensor and yaw rate sensor to detect the cross motion amount of vehicle and the amount of exercise of steering direction.
The vehicle of the 3rd example embodiment can be modified to and comprise the SBW accessory feed.In this case, for example, if the voltage of SBW accessory feed has descended owing to the reason of short or other power supply troubles of the electric power of SBW accessory feed, therefore and SBW-ECU1000 and SBW actr 1200 utilize the electric power of SBW accessory feed not move, and then the controller of vehicle of second example embodiment can move effectively.
The voltage of the voltage of SBW accessory feed and/or ECB cond is monitored by power supply supervisory circuit.When the voltage that detects the voltage of SBW accessory feed and/or ECB cond when power supply supervisory circuit was under the predetermined voltage level, the control of P-ON gear was performed.For described configuration, when the power supply trouble of main power source occurring, before the electric power of the electric power of SBW accessory feed and/or ECB cond was depleted, the control of P-ON gear was performed, and therefore can keep the stabilized conditions of vehicle.
Although described the present invention, should be understood that the present invention is not limited to described embodiment or structure according to its example embodiment.On the contrary, the present invention is intended to cover the configuration of various improvement and equivalence.In addition, although the various elements of example embodiment show with the multiple combination of example and structure, comprise more, still less or only other combinations of discrete-component and structure are arranged also in essence of the present invention and scope.
